Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
For non EU countries the present document may be used for regulatory (Type Approval) purposes.
Where equipment compliant with the present document is intended for fitment into vehicles, then it is subject to
automotive EMC type approval and has to comply with directive 95/54/EC [6]. For use on vehicles outside the scope of
95/54/EC [6] compliance with an EMC directive/standard appropriate for that use is required.
The present document is part 1 of a multi-part deliverable covering Electromagnetic compatibility and Radio spectrum
Matters (ERM); Short Range Devices; Road Transport and Traffic Telematics (RTTT); Radar equipment operating in
the 76 GHz to 77 GHz range, as identified below:
Part 1: "Technical characteristics and test methods for radar equipment operating in the 76 GHz to
77 GHz range";
Part 2: "Harmonized EN covering essential requirements of article 3.2 of the R&TTE Directive".

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
antenna scan duty factor: ratio of the area of the beam (measured at its 3 dB point) to the total area scanned by the
antenna (as measured at its 3 dB point)
assigned frequency band: frequency band within which the device is authorized to operate
associated antenna: antenna and all its associated components which are designed as an indispensable part of the
equipment
average time: time interval on which a mean measurement is integrated
blanking period: time period where no intentional emission occurs
channel dwell duty: ratio of the time of uninterrupted continuous transmission within a given frequency channel to the
channel repetition interval (= channel dwell time/channel repetition interval)
channel dwell time: accumulated amount of transmission time of uninterrupted continuous transmission within a single
given frequency channel and within one channel repetition interval
duty cycle: the ratio of the total on time of the "message" to the total off-time in any one hour period
Equipment Under Test (EUT): radar sensor including the integrated antenna together with any external antenna
components which affect or influence its performance
equivalent isotropically radiated power (e.i.r.p.): total power or power density transmitted, assuming an isotropic
radiator
NOTE: e.i.r.p. is conventionally the product of "power or power density into the antenna" and "antenna gain".
e.i.r.p. is used for both peak or average power and peak or average power density.
equivalent pulse power duration: duration of an ideal rectangular pulse which has the same content of energy
compared with the pulse shape of the EUT with pulsed modulation or time gating
2
far field measurements: distance "X" should be a minimum of 2d /λ , where d = largest dimension of the antenna
aperture of the EUT
maximum safe level for radiated power density: level which can be transmitted in accordance with the current
recommended safety levels in EN 50166-2 should be done on the vehicle

mean power: supplied from the antenna during an interval of time sufficiently long compared with the lowest
frequency encountered in the modulation taken under normal operating conditions (see Radio Regulations [8])
NOTE: For pulsed systems the mean power is equal the peak envelope power multiplied by the time gating duty
factor. For CW systems without further time gating the mean power is equal the transmission power
without modulation.
on-off gating: methods of transmission with fixed or randomly quiescent period that is much larger than the PRF
operating frequency (operating centre frequency): nominal frequency at which equipment is operated
NOTE: Equipment may be able to operate at more than one operating frequency.
operating frequency range: range of operating frequencies over which the equipment can be adjusted through
switching or reprogramming or oscillator tuning
NOTE 1: For pulsed or phase shifting systems without further carrier tuning the operating frequency range is fixed
on a single carrier line.
NOTE 2: For analogue or discrete frequency m
